Almost half of all cyclists in London have been knocked off their bicycle by a car, van or lorry, new figures reveal.

Those most at risk are in the 25-34 age group, with 40 per cent admitting they have been knocked off their bike at least once.

The survey also showed more than twice as many cyclists in this age group have been knocked off their bike in the last month compared to cyclists in the 45-54 age bracket.

Altogether, 42 per cent have come off their bikes in collisions with other road users at some point.

The results of the survey highlight the dangers facing cyclists on London roads, with just under one third of those polled revealing that they have been knocked off their bicycles or had a close shave with a vehicle in the past month alone.

The research was done by specialist cycle insurer, Protectyourbubble.com.

Its survey also revealed that 13 per cent of cyclists have accidentally damaged a vehicle while out riding, and 16 per cent confessing to hitting a pedestrian with their bike.

Stephen Ebbett, director of Protectyourbubble.com said: “Despite significant investment by borough councils to improve road safety for cyclists, it is worrying how many London bike users have been involved in incidents with other road users. It also might raise a few eyebrows just how many Londoners have been knocked off their bikes on more than one occasion. The fact is that London roads are dangerous places and cyclists need to ensure they are safe and prepared at all times.”

Last week, actor and dancer Sofoklis Kostoulas, who performed at the Olympics cultural festival became the 12th cyclist to be killed in London this year.

The 31-year-old, from Bow, died in hospital eight days after being crushed beneath the wheels of a HGV lorry despite several attempts by medics to save his life.

The Greek national had appeared in the English National Ballet production of Like A Fish Out Of Water which was staged at the Uxbridge lido and at Hampton pool as part of the 2012 Cultural Olympiad.
